How to create an alias on two indexes with logstash? -


in cluster working on there 2 main indexes, let's indexa , indexb these 2 indexes indexed each day normaly have indexa-{+yyyy.mm.dd} , indexb-{+yyyy.mm.dd}.

what want have 1 alias gathers indexa-{+yyyy.mm.dd} , indexb-{+yyyy.mm.dd} , named alias-{+yyyy.mm.dd}.

does know how gather 2 indexes in 1 alias logstash ?

thank in advance

as far know, there's no way logstash directly. can external program using elasticsearch api: http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-aliases.html

for example:

curl -xpost 'http://localhost:9200/_aliases' -d ' {     "actions" : [         { "add" : { "index" : "indexa-2015.01.01", "alias" : "alias-2015.01.01" } },         { "add" : { "index" : "indexb-2015.01.01", "alias" : "alias-2015.01.01" } }     ] }'

the other option (which doesn't meet requirements of having named alias-yyyy.mm.dd) use index template automatically adds alias when index created.

see http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-templates.html:

curl -xput localhost:9200/_template/add_alias_template -d '{   "template" : "index*",   "aliases" : {     "alias" : {}     }   } }'

this add alias of alias every index named index*.

you can of queries against alias. can setup alias in kibana index , things work right.
